87 duel exhaust question

Hey guys, i want to instal a True duel exhaust in my 87. My problem is that the stock exhaust system is a 2-1-2 exhaust. The reason the pipes go from 2 to 1 is because of the CAT and oxygen sensor.

If i run duel exhaust, how will i install the oxygen sensor? just in one pipe?

A good flowing single 3 inch exhaust is all you really need. Just get a single in dual out muffler and run 2.25-2.5 inch tailpipes with your choice of tips. There is really not much point to having true duals on our trucks. Conanski is right though, you only need the 02 in one bank. Here is mine with a SIDO Magnaflow.

Go find a truck with an AOD and take the trans and crossmember, TV cable and TB bracket, and front and rear driveshafts.

Your best bet is to swap in a non-computer controlled transmission such as an AOD. The E4OD and 4R series are computer controlled. Even then you could use one of them with an aftermarket trans. controller from Baumannator. Or keep you current transmission and swap in an over/underdrive from Gear Vendors.

Each path has it's advantages. Each will take money. Depending on how much you drive the truck it could take a long time to see any payback.
